The brain cannot multitask. Multitasking, when it comes to paying attention, is a myth. The brain naturally focuses on concepts sequentially, one at a timeโฆTo put it bluntly, research shows that we canโt multitask. We are biologically incapable of processing information-rich inputs simultaneouslyโฆStudies show that a person who is interrupted takes 50 percent longer to accomplish a task. Not only that, he or she makes up to 50 percent more errors.

But once you've found a solution, there is no need to continue the adaptive behavioral parrying, which is bioenergetically very expensive to maintain. We are built to find answers, then hang on to them as long as we can.
